Explanation
A one-time password (OTP), also called a dynamic password, is valid for a single authentication session or transaction only. Because it changes every log-on, even if an attacker intercepts or steals it, it cannot be reused - providing maximum protection against replay attacks. Static passwords remain the same across sessions (most common, least secure). Passphrases are long static phrases that are harder to guess but still reusable. Cognitive passwords rely on questions about personal facts. None of those match 'a new password for every log-on,' which is the defining property of a one-time/dynamic password.
